The special fix is the 0x0080 Use PC FPS Calculation. I tried using the Eternal SPU and the SPU Lite with the following settings (see attachment), however whenever the audio plays, it skips and stutters during the longer codec conversations moreso than with P.E.Op.S. DSound Audio Driver 1.9 (almost perfect with this one for me). I tried adjusting the buffer but no good here...
It's not too big a deal, since there aren't too many FMVs in the game. But thank you for your help!
